How do I start MDCS

Hello!

I recently (tried to) installed a Matlab MDCS. After few tries, the installation went successfull and the license file is integrated. At this time, everything was nice except that I didn't run matlab yet.

To test it, I started $matlabroot\bin\matlab.exe. When doing that, I receive an error (License Manager error -18) and I see this in the license manager log: "16:56:20 (MLM) UNSUPPORTED: "MATLAB" (PORT_AT_HOST_PLUS ) xxxxx@xxxxxx (License server system does not support this feature. (-18,327))"

Can anyone help me point where is the trouble?

- Is there anything wrong with my license file?

- As this concerns MDCS, is it normal that $matlabroot\bin\matlab.exe does not start?

- How can I start the MDCS and check everything is fine?

Thanks for any help!

Here is "License Manager Error 18" troubleshooting.

First, could you restart license manager and run MATLAB again?

This is a link which shows hot to restart. https://www.mathworks.com/matlabcentral/answers/102968-how-do-i-start-or-stop-the-mathworks-flexnet-license-manager

Thanks for your answer but it didn't help so much. Actually, the license manager has restarted few times but I don't think it's the issue has it get the requests.

The full error message is: " Make sure the license file on the MATLAB client matches the license file of the license server and that the licenser server has been started properly". I suppose the error is due to the first part

Next question is: Should I set the license file somewhere specific on the client? At this time, I try to start it from the server itself

Let me confirm. Did you install MDCS in your client machine or also install in your compute nodes (servers)? Related to your second question, you should set a license file (license.dat) in the license server which runs MATLAB License Server, and another license file (network.lic) in the compute nodes.

The hostname of your license server, ID, and ports written in license.dat must be the same as those written in the network.lic.
